AD9518-3 Rev. C is a 6-output clock generator with integrated 2.0 GHz VCO. It features low phase noise, phase-locked loop (PLL), various reference input options, programmable delays, digital or analog lock detect, etc.
The AD9518-3 provides a multi‑output clock distribution function with sub‑picosecond jitter performance. It integrates a phase‑locked loop and an on‑chip VCO that tunes from 1.75 GHz to 2.25 GHz, and can also accept an external VCO/VCXO up to 2.4 GHz. Six LVPECL outputs are arranged in three pairs, each supporting programmable division and coarse phase delay.
Typical applications include low‑jitter clock distribution for 10/40/100 Gb/s networking line cards, high‑speed ADC/DAC converters, wireless transceivers, and high‑performance instrumentation. The device operates from a 3.3 V supply over an industrial temperature range of –40 °C to +85 °C.
